CMDBuild Memory Leak

Old Versions
#1

Hi, 

in my application I use webservice soap interface to create and update cards in CMDBuild (2.3.4).

In particular every night I've to update a lot of cards and realtions (about 20K cards).

the problem sometimes (every four/five days) CMDBuild hits an OutOfMemoryError, and we've to restart it.

Somebody else has experienced a similar behaviour?

thanks in advance

Hi
